If you have never done it, and love mechanical time pieces, you might enjoy going to the Royal Observatory at Greenwich.
Determining longitude was a problem that had never been solved. Ships got lost at sea and fleets of ships crashed into rocks at night or in a storm. Everybody thought a star chart or lunar formula would solve the problem. John Harrison, a watch maker determined that longitude could be solved with an accurate time piece that would work even within a raging storm. He spent his life trying to make the perfect time piece. Harrison's multiple attempts are on display at the observatory. He was finally able to solve longitude.
